Introduction

Traffic Noise Analysis Report 5 I-94 St. Michael to Albertville

Introduction

The purpose of this noise report is to evaluate and document the effect of

the proposed Interstate 94 (I-94) St. Michael to Albertville Project (S.P.

8680-172) on traffic generated noise levels. The proposed project is not

programmed for construction. An Environmental Assessment Worksheet

(EAW) has been prepared for the proposed project to address State of

Minnesota environmental review requirements. The proposed project meets

the definition for a mandatory EAW under Minnesota Rules 4410.4300

Subpart 22 (B) (for construction of additional travel lanes on an existing road

for a length of one or more miles). The project proposer and responsible

governmental unit (RGU) is the Minnesota Department of Transportation

(MnDOT).

This traffic noise analysis addresses State of Minnesota noise standards. The

project does not include federal-aid funding. An Interstate Access

Modification Request (IAMR) approval will be required from the Federal

Highway Administration (FHWA) in the future prior to construction. An

environmental review under the National Environmental Policy Act (NEPA)

will be required in conjunction with the IAMR. The traffic noise analysis will

be updated in the future as part of the federal environmental review process

to address FHWA requirements.

This traffic noise analysis was completed following the procedures and

guidance described in the Minnesota Department of Transportation

(MnDOT) traffic noise policy (MnDOT Noise Policy for Type I Federal-aid

Projects as per 23 CFR 772, effective June 15, 2015).1 MnDOT’s Highway

Noise Policy applies to all projects under MnDOT authority.

General Project Description

The project is in the cities of St. Michael and Albertville, Wright County,

Minnesota (see Figure 1 and Figure 2). The proposed project would include

reconstruction of I-94 from west of the County State Aid Highway

(CSAH) 19 interchange to CSAH 37 in Albertville, reconstruction of the I-94

bridges over CSAH 19, construction of an eastbound collector-distributor

1 The I-94 St. Michael to Albertville Project Traffic Noise Analysis was completed under the 2015

MnDOT Noise Policy. The 2015 MnDOT Noise Policy is available online on the MnDOT Office of

Environmental Stewardship webpage at http://www.dot.state.mn.us/environment/noise/pdf/mndot-

Introduction


road between the CSAH 19 and CSAH 37 interchanges, construction of an

additional travel lane along eastbound and westbound I-94 between

CSAH 37 and TH 241 in St. Michael, and reconstruction of the TH 241

interchange. The total project length along I-94 from west of the CSAH 19

interchange to the TH 241 interchange is approximately 4.6 miles. The total

length of the project along TH 241 is approximately 0.5 miles.

Background Information on Noise

Noise is defined as any unwanted sound. Sound travels in a wave motion and

produces a sound pressure level. This sound pressure level is commonly

measured in decibels. Decibels (dB) represent the logarithm of the ratio of a

sound energy relative to a reference sound energy. For highway traffic noise,

an adjustment, or weighting, of the high- and low- pitched sound is made to

approximate the way that an average person hears sound. The adjusted sound

levels are stated in units of “A-weighted decibels” (dBA). A sound increase

of 3 dBA is barely noticeable by the human ear, a 5 dBA increase is clearly

noticeable, and a 10 dBA increase is heard as twice as loud. For example, if

the sound energy is doubled (i.e., the amount of traffic doubles), there is a

3 dBA increase in noise, which is just barely noticeable to most people. On

the other hand, if traffic increases by a factor of ten times, the resulting

sound level will increase by about 10 dBA and be heard to be twice as loud.

In Minnesota, traffic noise impacts are evaluated by measuring and/or

modeling the traffic noise levels that are exceeded 10 percent and 50 percent

of the time during the hours of the day and/or night that have the loudest

traffic scenario. These numbers are identified as the L10 and L50 levels,

respectively. The L10 value is the noise level that is exceeded for a total of 10

percent, or 6 minutes, of an hour. The L50 value is the noise level that is

exceeded for a total of 50 percent, or 30 minutes, of an hour.

monitoring/noise-program.html.

Along with the volume of traffic and other factors (e.g., topography of the

area and vehicle speed) that contribute to the loudness of traffic noise, the

distance of a receptor from a sound’s source is also an influential factor.

Sound level decreases as distance from a source increases. A general rule

regarding sound level decrease due to increasing distance from a line source

(roadway) that is commonly used is: beyond approximately 50 feet from the

sound source, each doubling of distance from the line source over hard

ground (such as pavement or water) will reduce the sound level by 3 dBA,

whereas each doubling of distance over soft ground (such as vegetated or

grassy ground) results in a sound level decrease of 4.5 dBA.

Introduction


Minnesota State Noise Standards

Minnesota state noise standards have been established for daytime and

nighttime periods. For residential land uses (identified as Noise Area

Classification 1 or NAC-1), the Minnesota state standards for L10 are 65 dBA

for daytime and 55 dBA for nighttime; the standards for L50 are 60 dBA for

daytime and 50 dBA for nighttime. The Minnesota Pollution Control Agency

(MPCA) defines daytime as 7:00 a.m. to 10:00 p.m. and nighttime from

10:00 p.m. to 7:00 a.m. Table 1 lists State noise standards. Minnesota state

noise standards apply to the outdoor atmosphere (i.e., exterior noise levels).

(2) NAC-2 includes retail and restaurants, transportation terminals, professional offices, parks,

recreational, and amusement land uses.

(3) NAC-3 includes industrial manufacturing, transportation facilities (except terminals), and utilities land

uses.

(4) Daytime hours are from 7:00 a.m. to 10:00 p.m.

(5) Nighttime hours are from 10:00 p.m. to 7:00 a.m.

State noise standards apply to interstate highways and trunk highway

facilities. The State noise standards apply to the project segment of I-94, the

proposed eastbound collector-distributor road in Albertville, and the

CSAH 19, CSAH 37, and TH 241 interchanges. Exemptions to State noise

standards are found in Minnesota Statutes 2000, Section 116.07 subd. (2a).

There it is stated the conditions and roadway types that are exempt from the

State noise standards.

Analysis Methodology



Affected Environment

The proposed I-94 St. Michael to Albertville Project is in Wright County in

the cities of St. Michael and Albertville. Existing lands adjacent to the project

segment of I-94 and the I-94/TH 241 interchange include residential,

commercial (retail and restaurant), business office, industrial, and agricultural

uses. Recreational uses in the study area include The Preserve Park located

along the south side of I-94 and Oakwood Parkway in St. Michael. Trails are

located along CSAH 37 and CSAH 19 in Albertville; along Barthel Industrial

Drive, south of I-94 and east of CSAH 37 in Albertville; and along 50th Street

Northeast at The Preserve Park in St. Michael.

Noise Monitoring

Noise Level Monitoring Results

Noise level monitoring is commonly performed during a noise study to

document existing noise levels and to validate the noise model for the project

(see discussion of “Field Measurements and Predicted Noise Levels” below).

Existing noise levels were monitored at three representative locations within

the project area. Noise monitoring locations are described below.

• Monitoring Site 1 (M-1) is located at a multi-family residential

property along the south side of I-94 and CSAH 37, west of the

CSAH 19 interchange in Albertville.

• Monitoring Site 2 (M-2) is located at a commercial business along the

north side of I-94, east of the CSAH 37 interchange in Albertville.

• Monitoring Site 3 (M-3) is located at a rural residential property along

the north side of I-94 near the St. Michael/Albertville municipal

boundary.

Daytime noise levels were collected in August 2016 at the three receptor

locations described above. Noise levels were monitored at each location

twice; once during the morning and again during the afternoon. A trained

noise monitoring technician was present at each session for the entire field

measurement session to ensure correct operation of the sound level meter

(SLM). The morning and afternoon monitored levels are presented below in

Table 2. Monitored daytime traffic noise levels ranged from 68.6 dBA (L10) to

74.7 dBA (L10).

Field Measurements and Predicted Noise Levels

Noise monitoring results are presented in Table 3 along with the computer

modeling results for existing daytime traffic noise levels. Computer modeling

results are based on classified traffic (e.g., cars, medium trucks, and heavy

trucks) observed during the field measurements. The speeds used for the

model predictions were posted speeds (e.g., 70 miles per hour on eastbound

and westbound I-94). Noise monitoring results presented in Table 3 are an

average of the applicable morning and afternoon field measurements

described above.

M-1 71.7 69.1 -2.6

M-2 74.0 76.3 2.3

M-3 69.2 72.8 3.6

A discrepancy equal to or less than 3.0 dBA between field measurements and

predicted levels is considered acceptable for noise model validation. The

predicted noise level at one field measurement location (Receptor M-3) was

0.6 dBA (L10) above the 3.0 dBA threshold for noise model validation. It is

considered better to over-predict uncorrected traffic noise levels, which

yields a worst-case scenario, compared to under predicting noise levels when



determining traffic noise impacts and mitigation effectiveness. Therefore, the

prediction model was utilized without corrections.

Worst Hourly Traffic Noise Analysis

In general, higher traffic volumes, vehicle speeds, and greater numbers of

heavy trucks increase the loudness of highway traffic noise. The worst hourly

traffic noise impact typically occurs when traffic is flowing more freely (e.g.,

level of service C conditions) and when heavy truck volumes are the greatest.

For determining the worst-case traffic noise hour for the proposed project,

traffic noise levels for six time periods were modeled at 40 representative

receptor locations within the project study area under existing conditions,

considering the appropriate classified traffic mix (i.e., cars, medium trucks,

heavy trucks)2, seasonal traffic variations where appropriate, and directional

split in traffic volume (i.e., eastbound I-94 versus westbound I-94). The

speeds used for the model predictions were posted speeds (i.e., 70 mph on

eastbound and westbound I-94).

The daytime L10 and L50 levels for each of the six modeled time periods are

summarized in Table 4. Based on this analysis, it was determined that the

12:00 p.m. to 1:00 p.m. period represents the worst-case traffic noise hour

during the daytime period. The 12:00 p.m. to 1:00 p.m. hour represents a

period of higher heavy truck volumes compared to other times of the day.

The 6:00 a.m. to 7:00 a.m. hour was identified as the loudest hour of the

nighttime period because of higher traffic volumes just prior to the start of

the morning rush hour.

2 Identification of the worst-case traffic noise hour based on April 2016 MnDOT vehicle classification

counts for I-94 west of CSAH 19 in Albertville (Weigh In Motion Site #37) and 2009 MnDOT vehicle

classification counts at the TH 241, CSAH 37, and CSAH 19 interchanges.

Traffic Noise Modeling

Noise modeling was done using the noise prediction program

“MINNOISEV31”, a version of the FHWA “STAMINA” model adapted by

MnDOT for use in Minnesota. This model uses traffic volumes, speed, class

of vehicle, and the typical characteristics of the roadway being analyzed (e.g.,

roadway horizontal and vertical alignment). The noise modeling assumed free

flow conditions through at-grade intersections on CSAH 19, CSAH 37, and

TH 241.

Traffic data for noise model input files included existing (2015) and future

(year 2040) No Build Alternative and Build Alternative forecast traffic

volumes for I-94, TH 241, CSAH 37, and CSAH 19. Year 2040 was

identified as the future year for analysis because this is the current horizon

year for land use plans, transportation planning, and travel demand forecasts

for the project area. The modeled speed on I-94 for existing conditions, the

2040 No Build Alternative, and the 2040 Build Alternative was 70 miles per

hour (mph). The modeled speed on CSAH 19 for existing conditions, the

2040 No Build Alternative, and the 2040 Build Alternative was 45 mph. The

modeled speed on CSAH 37 varied from 40 mph for the segment between

CSAH 19 and I-94, and 55 mph for the segment east of the I-94/CSAH 37

interchange. The modeled speed on TH 241 for existing conditions, the 2040

No Build Alternative, and the 2040 Build Alternative was 55 mph.

The daytime hour of analysis was the 12:00 p.m. to 1:00 p.m. hour (see

Worst Hourly Traffic Noise Analysis discussion above). The 12:00 p.m. to

1:00 p.m. hour was determined to represent approximately 5.4 percent of the

daily traffic volumes for the project segment of I-94. The nighttime hour of

analysis was the 6:00 a.m. to 7:00 a.m. hour. The 6:00 a.m. to 7:00 a.m. hour

was determined to represent approximately 5.9 percent of daily traffic

volumes for the project segment of I-94.

Predicted Noise Levels and Noise Impacts



Noise Receptors

Traffic noise impacts were assessed by modeling noise levels at receptor sites

likely to be affected by the proposed project. Traffic noise levels were

modeled at more than 450 receptor locations along the project segment of

I-94 representing residential, commercial (retail, restaurants), business office,

recreational (parks and trails), and industrial uses. Modeled receptor locations

are illustrated in Figure A-1 through Figure A-9, Appendix A. Table B-1,

Appendix B (daytime) and Table B-2, Appendix B (nighttime) identifies land

uses and state noise area classifications (NAC) for each modeled receptor

location.

Noise Model Results

Table B-1, Appendix B (daytime) and Table B-2, Appendix B (nighttime)

tabulates the results of the noise modeling analysis for existing conditions,

the 2040 No Build Alternative, and the 2040 Build Alternative. The results of

the traffic noise modeling analysis are summarized below.

Existing Conditions Results

Existing daytime L10 noise levels at modeled receptor locations range from

54.7 dBA to 84.9 dBA, whereas daytime L50 noise levels range from 52.2 dBA

to 78.7 dBA. Existing nighttime L10 modeled noise levels range from 54.8

dBA to 84.8 dBA, whereas nighttime L50 noise levels range from 52.4 dBA to

77.7 dBA. Modeled daytime traffic noise levels exceed State daytime L10

standards at 256 modeled receptor locations, and exceed State daytime L50

standards at 329 receptor locations. Modeled nighttime traffic noise levels

exceed State nighttime L10 standards at 394 modeled receptor locations, and

exceed State nighttime L50 standards at 419 modeled receptor locations.

2040 No Build Alternative Results

Future (2040) daytime L10 modeled noise levels under the No Build

Alternative are predicted to range from 55.8 dBA to 87.0 dBA, whereas

daytime L50 noise levels are predicted to range from 53.6 dBA to 80.2 dBA.

Future nighttime L10 modeled noise levels under the No Build Alternative are

predicted to range from 55.9 dBA to 85.8 dBA, whereas nighttime L50 noise

levels are predicted to range from 53.7 dBA to 79.2 dBA. Modeled daytime

traffic noise levels are predicted to increase by 0.9 dBA to 2.8 dBA (L10)



under the 2040 No Build Alternative compared to existing conditions. This

increase is likely due to projected traffic growth within the project area.

Modeled daytime traffic noise levels are projected to exceed State daytime L10

standards at 285 modeled receptor locations under 2040 No Build

Alternative. Modeled daytime traffic noise levels are projected to exceed State

daytime L50 standards at 376 modeled receptor locations. Modeled nighttime

traffic noise levels are projected to exceed State nighttime L10 standards at

409 modeled receptor locations under the 2040 No Build Alternative, and

exceed State nighttime L50 standards at 429 modeled receptor locations under

the 2040 No Build Alternative.

2040 Build Alternative Results

Future daytime L10 modeled noise levels under the 2040 Build Alternative are

predicted to range from 55.8 dBA to 88.7 dBA, and L50 modeled noise levels

are projected to range from 53.9 dBA to 81.3 dBA. Future nighttime L10

the 2040 Build Alternative, and exceed State nighttime L50 standards at 433

modeled receptor locations under the 2040 Build Alternative.

Consideration of Noise Abatement



The MnDOT Highway Noise Policy (June 2015) describes noise abatement

measures that are to be considered when a traffic noise impact has been

identified with a highway improvement project (i.e., modeled traffic noise

levels exceed State daytime and/or nighttime standards). These noise

abatement measures are described below.

• Construction of noise barriers, including acquisition of property

rights, either within or outside the highway right of way. Landscaping

is not a viable noise abatement measure.

• Traffic management measures, including, but not limited to, traffic

control devices and signing for prohibition of certain vehicle types,

time-use restrictions for certain vehicle types, modified speed limits,

and exclusive lane designations.

• Alteration of horizontal and vertical alignments.

• Acquisition of real property or interests therein (predominantly

unimproved property) to serve as a buffer zone to preempt

development which would be adversely impacted by traffic noise.

• Noise insulation of certain facilities, including: auditoriums, day care

centers, hospitals, libraries, medical facilities, places of worship,

public meeting rooms, public or nonprofit institutional structures,

radio studios, recording studios, schools, and television studios.

Noise Barrier Evaluation

The policies and procedures for evaluating noise barrier feasibility and

reasonableness are set forth in Section 5.2 (Feasibility) and Section 5.3

(Reasonableness) of the MnDOT Highway Noise Policy (June 2015). The factors

for determining noise barrier feasibility and reasonableness as described in

the MnDOT Highway Noise Policy are summarized below.

Noise Barrier Feasibility

Noise barrier feasibility is determined based on a consideration of two

factors: 1) acoustic feasibility and 2) engineering feasibility.

• Acoustic feasibility: For a noise barrier to be considered

acoustically effective, it must achieve a noise reduction of at least

5 dBA at the impacted receptors for those receptors to be considered

benefited by a noise barrier. Not every impacted receptor must



receive this minimum 5 dBA reduction; however, at least one

impacted receptor must meet the minimum 5 dBA reduction for a

noise barrier to achieve acoustic feasibility.

• Engineering feasibility: Engineering feasibility addresses whether it

is possible to design and construct a proposed noise abatement

measure. A sample of potential constructability considerations

includes safety, topography, drainage, utilities, and maintenance

considerations. Engineering considerations are also taken into

consideration in determining noise barrier height. MnDOT has

established a maximum noise barrier height of 20 feet above the

finished ground line at the noise barrier.

The feasibility of noise barrier construction is sometimes dependent on

design details that are not known until the final design phase of the project.

For this traffic noise analysis, it was assumed that noise barriers were feasible

with respect to engineering feasibility/constructability considerations. Gaps

were included in the modeled noise barriers to accommodate driveway

connections and intersecting side streets where appropriate. It was also

assumed that utilities located within existing right of way could be relocated

to accommodate modeled noise barriers, and existing and proposed drainage

could be maintained. All modeled noise barriers were located within existing

or proposed highway right of way limits.

Noise Barrier Reasonableness

Noise barrier reasonableness decisions are based on a consideration of three

reasonableness factors: 1) noise reduction design goal, 2) cost effectiveness,

and 3) the viewpoint of benefited residents and property owners.

Noise Reduction Design Goal

A minimum 7 dBA reduction must be achieved for at least one benefited

receptor behind the noise barrier to meet noise reduction design goals.

Cost Effectiveness

To be considered cost-effective, the cost per individual benefited receptor

(e.g., residence, commercial entity, industrial entity) should be equal to, or

less than $43,500. To assess cost effectiveness, at least one benefited receptor

behind the noise barrier must meet the noise reduction design goal described

above. The following formula is used to determine the cost-effectiveness of

the barrier:



The cost-effectiveness index is equal to the cost of the noise barrier divided by the number of

individual benefited receptors (i.e., residences, commercial entities, industrial entities) that

are predicted to experience noise level reductions of 5 dBA or more. Only those receptors

that experience a 5 dBA or greater decibel decrease are considered in this formula. The

result is a cost per benefited receptor value (residence, commercial entity, or industrial entity

represented by each modeled receptor). The cost of a noise barrier is calculated using $20

per square foot of barrier, based on historical data over the five-year period from 2005-

2010. To be considered cost-effective, the cost per individual benefited receptor must be

equal to or less than $43,500 per receptor.

There are several steps to assessing the cost effectiveness of noise barriers.

First, the cost-effective noise barrier height is determined for each segment

of the project area, beginning with the evaluation of a 20-foot tall noise

barrier (MnDOT’s maximum height; see discussion of engineering feasibility

above). If a 20-foot tall noise barrier meets the reasonableness criteria and is

feasible, it would be proposed for construction. If the 20-foot tall barrier

meets the noise reduction design goal but does not meet the cost

effectiveness criteria, then noise barrier heights less than 20 feet are studied.

If a noise barrier height less than 20 feet meets the reasonableness criteria

and is feasible, it would then be proposed for construction. Noise barrier

cost effectiveness is studied up to the point where a modeled barrier does

not meet the noise reduction design goal of a minimum 7 dBA reduction for

at least one benefited receptor.

Viewpoint of Benefited Residents and Property Owners

The third criterion in determining noise barrier reasonableness is the

viewpoint of benefited residents and property owners. A benefited property

is defined as a receptor adjacent to a proposed noise abatement measure that

receives a noise reduction equal to or greater than 5 dBA. If benefited

residents and property owners indicate that a proposed noise barrier is not

desired, then the noise barrier is removed from further consideration and

would not be constructed with the project.

There are two steps in determining the desires of the benefited property

owners and residents regarding the construction of a proposed noise

abatement measures. First, the viewpoint of benefited property owners and

residents is solicited through a public involvement process (e.g., open house

meeting, direct mailing of a solicitation form). Second, the input received

from benefited property owners and residents through this public

involvement process is expressed in a vote that is weighted as follows:

The owner of a benefited property immediately adjacent to the highway right of way for the

proposed project (i.e., first-row properties) receives 4 points and the resident (owner or



renter) receives 2 points. The owner/resident of a benefited property receives a total of 6

points.

The owner of a benefited property not immediately adjacent to the highway right of way for

the proposed project (e.g., second-row properties, third-row properties) receives 2 points and

the resident (owner or renter) receives 1 point. The owner/resident of a benefited property

receives a total of 3 points.

When there is no outdoor area of frequent human use associated with a benefited property,

the owner of the benefited property receives a total of 4 points if the property is located

immediately adjacent to the highway right of way (i.e., first-row properties). If the property

is not immediately adjacent to the highway right of way (i.e., second-row properties, third-

row properties), the owner of the benefited property receives a total of 2 points.

Only those benefited property owners and residents, including individual

units of multi-family residential buildings that are benefited receptors,

regardless of floor location (e.g., first floor, second floor, etc.), have a vote

according to the point system described above. Non-benefiting receptors do

not receive points. The MnDOT Highway Noise Policy allows for up to two

solicitation periods to request votes and determine the outcome regarding

proposed noise abatement measures.

• Initial Solicitation: If 50 percent or more of all possible voting

points from eligible voters are received after the initial request for

votes, the majority of points (based upon the votes received)

determine the outcome of the noise barrier. If less than 50 percent of

the possible voting points for a barrier are received after this initial

request, then a second ballot will be distributed to the benefited

property owners who did not respond.

• Second Request: If 25 percent or more of all possible points for a

barrier are received after the second request for votes, then the

outcome is determined by the majority of votes received. If less than

25 percent of total possible points for a noise barrier are received

after the second request for votes, then the barrier will not be

constructed. If there is a tie, where there are equal numbers of points

for and against a noise barrier, the noise barrier will be constructed.

Noise Wall Analysis Results

Noise barriers (i.e., noise walls) were evaluated at all modeled receptor

locations adjacent to the project segment of I-94 and the I-94/TH 241

interchange where traffic noise levels are predicted to exceed State daytime

and/or nighttime L10 and/or L50 noise standards under the 2040 Build



Alternative. The locations of modeled noise walls are illustrated in Figure

A-1, Appendix A through Figure A-9, Appendix A.

Noise wall cost-effectiveness results are tabulated at the end of this report in

Appendix C. Multiple noise wall configurations were evaluated (i.e., wall

lengths and heights) where applicable. The results presented below represent

the most acoustically effective and/or cost effective noise wall

configurations. Results for a 20-foot high noise wall are described with each

modeled wall first, followed by a discussion of additional wall heights less

than 20 feet where applicable. The discussion of noise wall modeling results

presented below includes only daytime results unless reasonableness was

achieved during the nighttime exclusively. For reference, nighttime noise wall

cost effectiveness results are also tabulated and presented at the end of this

report in Appendix C. Results of daytime noise wall cost effectiveness for the

project are consistent with noise wall cost effectiveness results for nighttime

conditions. The following discussion of noise wall analysis results refers to

L10 levels only.

Modeled Noise Wall A1 (North Side of I-94, West of CSAH 19)

(Receptors 1 through 6)

Modeled Noise Wall A1 is along the north side of I-94, west of CSAH 19 in

Albertville. The eastern terminus of Modeled Noise Wall A1 begins

approximately 1,930 feet west of CSAH 19. Modeled Noise Wall A1 is

approximately 1,005 feet long (see Figure A-1, Appendix A).

The approximately 1,005-foot long, 20-foot high noise wall provides a

reduction in daytime traffic noise levels of 0 dBA to 5.6 dBA (see Table C-1,

Appendix C). The approximately 1,005-foot long, 20-foot high modeled

noise wall does not meet MnDOT’s minimum 7 dBA noise reduction goal to

be considered reasonable. Therefore, the analyzed noise wall is not proposed.

Modeled Noise Wall A2 (Northwest Quadrant, I-94/CSAH 19

Interchange) (Receptors 7, 8, and TR21 through TR23)

Modeled Noise Wall A2 is in the northwest quadrant of the I-94/CSAH 19

interchange in Albertville. Modeled noise levels at Receptor 7 and Receptor 8

are projected to be below State daytime and nighttime standards under the

2040 Build Alternative for NAC-2; however, modeled noise levels at

representative receptor locations along the CSAH 19 trail (TR21, TR22, and

TR23) are projected to exceed State daytime and nighttime standards.

Modeled Noise Wall A2 is approximately 1,465 feet long (see Figure A-1,

Appendix A).




reduction in daytime traffic noise levels of 0 dBA to 0.2 dBA (see Table C-3,

Appendix C). The approximately 1,465-foot long, 20-foot high modeled

noise wall does not meet MnDOT’s minimum 5 dBA noise reduction to be

considered acoustically feasible. Therefore, the analyzed noise wall is not

proposed.

Modeled Noise Wall A3 (West Side of CSAH 19, North of I-94) (Receptors

TR21 through TR23)

Modeled Noise Wall A3 is located along the west side of CSAH 19, from the

entrance ramp to westbound I-94 to the entrance to the Albertville Outlet

Mall. Modeled Noise Wall A3 is in the boulevard area between the CSAH 19

trail and the southbound CSAH 19 travel lanes, and is approximately 610 feet

long (see Figure A-1, Appendix A).

The approximately 610-foot long, 20-foot high noise wall provides a

reduction in daytime traffic noise levels of 6.5 dBA to 10.0 dBA. The

approximately 610-foot long, 20-foot high noise wall would cost $298,470

and includes 610 feet of glue laminated rub rail at a cost of $115 per linear

foot.3 The cost-effectiveness of the approximately 610-foot long, 20-foot

high noise wall is $99,490 per benefited receptor (see Table C-5, Appendix

C). The approximately 610-foot long, 20-foot high noise wall does not meet

MnDOT’s cost-effectiveness criteria; therefore, the analyzed noise wall is not

proposed.

Based on the MnDOT Noise Policy of no more than one receptor per 200

feet of trail, and with no other adjacent benefited receptors, the maximum

possible noise wall height adjacent to a trail that can meet MnDOT’s cost

effectiveness criteria is a 10-foot high noise wall. Therefore, a 10-foot high

noise wall was evaluated.



approximately 610-foot long, 10-foot high noise wall would cost $192,150,


foot. The cost-effectiveness of the approximately 610-foot long, 10-foot high

noise wall is $64,050 per benefited receptor (see Table C-6, Appendix C).

The approximately 610-foot long, 10-foot high noise wall does not meet

An 8-foot high noise wall was identified as the lowest possible noise wall

height adjacent to the trail that would meet MnDOT’s 7dBA noise reduction

design goal. Therefore, an 8-foot high noise wall was modeled.

The approximately 610-foot long, 8-foot high noise wall provides a reduction

in daytime traffic noise levels of 5.0 dBA to 6.1 dBA (see Table C-7,

Appendix C). The approximately 610-foot long, 8-foot high modeled noise

wall does not meet MnDOT’s minimum 7 dBA noise reduction goal to be

considered reasonable. Therefore, the analyzed noise wall is not proposed.

Modeled Noise Wall B1 (South Side of I-94, West of CSAH 19) (Receptors

9 through 152 and TR1 through TR20)

Modeled Noise Wall B1 is located along the south side of I-94, west of

CSAH 19 in Albertville. Modeled Noise Wall B1 begins west of CSAH 19

and extends to the east to the southwest quadrant of the I-94/CSAH 19

interchange. Modeled Noise Wall B1 is approximately 5,080 feet long (see

Figures A-1, A-2, and A-3, Appendix A).

A portion of Modeled Noise Wall B1 is located inside the clear zone along

eastbound I-94. This is necessary to increase the top of wall elevation to

provide additional shielding for adjacent receptors. The length of Modeled

Noise Wall B1 within the clear zone is 3,635 feet. The estimated total cost

for Noise Wall B1 includes a glue laminated rub rail along the noise wall at a

cost of $115 per linear foot.


reduction in daytime traffic noise levels of 0 dBA to 4.5 dBA (see Table

C-11, Appendix C). The approximately 5,080-foot long, 20-foot high noise

wall would cost $2,434,345, and includes 3,635 feet of glue laminated rub rail

at a cost of $115 per linear foot. CSAH 37 is between the Modeled Noise

Wall B1 and adjacent receptor locations. CSAH 37 produces relatively high

traffic noise levels, reducing the effectiveness of Modeled Noise Wall B1.

The approximately 5,080-foot long, 20-foot high modeled noise wall does

not meet MnDOT’s minimum 5 dBA noise reduction to be considered

acoustically feasible. Therefore, the analyzed noise wall is not proposed.

Modeled Noise Wall B2 (West Side of CSAH 19, South of I-94) (Receptors

151 and 152, TR27 through TR29)

Modeled Noise Wall B2 is located along the west side of CSAH 19 between

the eastbound I-94 exit ramp and CSAH 37. Modeled Noise Wall B2 is in the

boulevard area between CSAH 19 and the trail. Gaps were included in

Modeled Noise Wall B2 to accommodate driveways to CSAH 19 and the



BNSF Railway. Modeled Noise Wall B2 is approximately 445 feet long (see

Figure A-1, Appendix A).

Modeled Noise Wall B3 (West Side of CSAH 19, Eastbound I-94 Exit

Ramp to Westbound I-94 Entrance Ramp) (Receptors TR24 through

TR26)

Modeled Noise Wall B3 is located along the west side of CSAH 19 between

the eastbound I-94 exit ramp and the westbound I-94 entrance ramp.

Modeled Noise Wall B3 is in the boulevard between the trail and the



southbound CSAH 19 travel lanes and is approximately 465 feet long (see

Figure A-1, Appendix A).

A 16-foot tall noise wall was evaluated for trail receptors along CSAH 19

between the eastbound I-94 exit ramp and the westbound I-94 entrance

ramp because this is the vertical clearance under the I-94 bridges over

CSAH 19.

C-21, Appendix C). The approximately 465-foot long, 16-foot high noise

wall would cost $194,275, and includes 465 feet of glue laminated rub rail at a

cost of $115 per linear foot. The approximately 465-foot long, 16-foot high

modeled noise wall does not meet MnDOT’s minimum 7 dBA noise

reduction goal to be considered reasonable. Therefore, the analyzed noise

wall is not proposed.

Modeled Noise Wall C (Northwest Quadrant, I-94/CSAH 37 Interchange)

(Receptors 170 and 171)

Modeled Noise Wall C is in the northwest quadrant of the I-94/CSAH 37

interchange in Albertville. Modeled Noise Wall C is approximately 1,485 feet



reduction in daytime traffic noise levels of 1.6 dBA to 2.9 dBA (see Table C-

23, Appendix C). The approximately 1,485-foot long, 20-foot high noise wall

Modeled Noise Wall D (South Side of I-94, CSAH 19 to CSAH 37)

(Receptor 153 through Receptor 169 and TR30 through TR40)

Modeled Noise Wall D is located along the south side of I-94 and the

proposed eastbound collector-distributor road between CSAH 19 and

CSAH 37 in Albertville. Modeled Noise Wall D is approximately 3,355 feet




approximately 3,355-foot long, 20-foot high noise wall would cost

$1,326,320. The cost-effectiveness of the approximately 3,355-foot long, 20-

foot high noise wall is $1,326,320 per benefited receptor (see Table C-25,



Appendix C). CSAH 37 is located behind Modeled Noise Wall D. CSAH 37

produces relatively high traffic noise levels, reducing the effectiveness of

Modeled Noise Wall D for adjacent receptor locations. The approximately

3,355-foot long, 20-foot high noise wall does not meet MnDOT’s cost-

effectiveness criteria; therefore, the analyzed noise wall is not proposed.

Because the 20-foot high noise wall was not cost effective, a lower wall

height was evaluated. The approximately 3,355-foot long, 18-foot high noise

wall provides a reduction in daytime traffic noise levels of 0.1 dBA to

6.4 dBA (see Table C-26, Appendix C). The approximately 3,355-foot long,

18-foot high noise wall would cost $1,196,280. As noted above, CSAH 37

produces relatively high traffic noise levels and reduces the effectiveness of

Modeled Noise Wall D. The approximately 3,355-foot long, 18-foot high

CSAH 37. Modeled noise wall E1 begins in the northeast quadrant of the

I-94/CSAH 37 interchange in Albertville and extends to the east to a point

Modeled Noise Wall E3, Option 1 was acoustically effective for Receptors

199 through 207 and Receptor 270 (i.e., a 5dBA reduction or greater with the

modeled noise wall). Receptors 199 through 207 and Receptor 270 represent

residential land uses adjacent to Needham Avenue, west of TH 241 (see

Figure A-6, Appendix A). Because Modeled Noise Wall E3, Option 1 was

not cost effective, a shorter wall length was evaluated along the north side of

I-94 adjacent to these residential receptors. Results of this analysis are

9-foot high noise wall would cost $59,000, and includes 200 feet of glue

laminated rub rail at a cost of $115 per linear foot. The cost-effectiveness of

the approximately 200-foot long, 9-foot high noise wall is $59,000 per

benefited receptor (see Table C-47, Appendix C). The approximately 200-

foot long, 9-foot high noise wall does not meet MnDOT’s cost-effectiveness

criteria; therefore, the analyzed noise wall is not proposed.


in daytime traffic noise levels of 6.8 dBA (see Table C-48, Appendix C). The

approximately 200-foot long, 8-foot high noise wall would cost $55,000, and



includes 200 feet of glue laminated rub rail at a cost of $115 per linear foot.

The approximately 200-foot long, 8-foot high modeled noise wall does not

meet MnDOT’s minimum 7 dBA noise reduction goal to be considered

reasonable. Therefore, the analyzed noise wall is not proposed.

Modeled Noise Wall F1 (Southeast Quadrant of I-94/CSAH 37

Interchange) (Receptors 175, 176, 177, and 178)

Modeled Noise Wall F1 is in the southeast quadrant of the I-94/CSAH 37

interchange in Albertville. Modeled Noise Wall F1 begins at CSAH 37 and

follows along the entrance ramp to eastbound I-94 to a point located

approximately 2,400 feet east of CSAH 37. Modeled Noise Wall F1 is

189, 190, 191, and 192)

Modeled Noise Wall F2 is located along the south side of I-94 between

CSAH 37 and TH 241. The western terminus of Modeled Noise Wall F2

begins approximately 2,400 feet east of CSAH 37 in Albertville. Modeled

Noise Wall F2 is approximately 2,440 feet long (see Figure A-4 and Figure A-

5, Appendix A).








Modeled Noise Wall F3 (South Side of I-94, East of CSAH 37) (Receptors

195, 196, and 197)

Modeled Noise Wall F3 is located along the south side of I-94 between

CSAH 37 and TH 241. The western terminus of Modeled Noise Wall F3

begins approximately 4,220 feet east of CSAH 37. Modeled Noise Wall F3 is

approximately 6,405 feet long (see Figure A-5 and Figure A-6, Appendix A).










Modeled Wall F4, Option 1 (South Side of I-94, West of TH 241)

(Receptors 208 through 268, 274, P1 through P6, and TR41 through

TR46)

Modeled Noise Wall F4, Option 1 is located along the south side of I-94,

west of TH 241 in St. Michael. Modeled Noise Wall F4, Option 1 begins

approximately 5,770 feet west of TH 241 and extends to the southwest

quadrant of the I-94/TH 241 interchange. Modeled Noise Wall F4, Option 1

is approximately 5,945 feet long (see Figure A-6 and Figure A-9, Appendix

A).

A portion of Modeled Noise Wall F4, Option 1 is located inside the clear

zone along eastbound I-94. This is necessary to increase the top of wall

elevation to provide additional shielding for adjacent receptors. The length of

Modeled Noise Wall F4, Option 1 within the clear zone is 3,740 feet. The

estimated total cost for Noise Wall F4, Option 1 includes a glue laminated

rub rail along the noise wall at a cost of $115 per linear foot.

meet MnDOT’s cost-effectiveness criteria; therefore, the analyzed noise wall

is not proposed.

Modeled Noise Wall F4, Option 1 was acoustically effective for four

receptors representing residential properties along 47th Lane Northeast

overlooking I-94 (Receptors 261, 262, 263, and 267). These receptors are in

the middle of Modeled Noise Wall F4, Option 1 (see Figure A-6, Appendix

A). Because the approximately 5,945-foot long, 20-foot high Modeled Noise

Wall F4, Option 1 was not cost effective, a shorter wall length was evaluated.

Results of this analysis are described below under “Modeled Noise Wall F4,

Option 2”.



Modeled Wall F4, Option 2 (South Side of I-94, West of TH 241)

(Receptors 242 through 268)

Modeled Noise Wall F4, Option 2 is located along the south side of I-94,

west of TH 241 in St. Michael. The western terminus of Modeled Noise Wall

F4, Option 2 is located approximately 4,700 feet west of TH 241. The

eastern terminus of Modeled Noise Wall F4, Option 2 is located

approximately 2,980 feet west of TH 241. Modeled Noise Wall F4, Option 2

is approximately 1,920 feet long (see Figure A-6, Appendix A).

A portion of Modeled Noise Wall F4, Option 2 is located inside the clear

zone along eastbound I-94. This is necessary to increase the top of wall

elevation to provide additional shielding for adjacent receptors. The length of

Modeled Noise Wall F4, Option 2 within the clear zone is 1,105 feet. The

estimated total cost for Noise Wall F4, Option 2 includes a glue laminated

rub rail along the noise wall at a cost of $115 per linear foot.

Because the 20-foot high noise wall was not cost effective, lower wall heights

were evaluated. The approximately 1,920-foot long, 18-foot high noise wall

provides a reduction in daytime traffic noise levels of 0.9 dBA to 6.1 dBA.

The approximately 1,920-foot long, 18-foot high noise wall would cost

$806,755 and includes 1,105 feet of glue laminated rub rail at a cost of $115

long, 18-foot high noise wall does not meet MnDOT’s minimum 7 dBA

noise reduction goal to be considered reasonable. Therefore, the analyzed

Modeled Noise Wall F5 is located along the west side of TH 241 south of the

eastbound I-94 exit ramp. Modeled Noise Wall F5 ends at the TH 241/

O’Day Avenue intersection (i.e., entrance to commercial land uses in the

southwest quadrant of the I-94/TH 241 interchange). Modeled Noise Wall



F5 is behind the curb along southbound TH 241 adjacent to a proposed trail,

and is approximately 305 feet long (see Figure A-9, Appendix A).

9-foot high noise wall would cost $89,975, and includes 305 feet of glue

laminated rub rail at a cost of $115 per linear foot. The cost-effectiveness of

the approximately 305-foot long, 9-foot high noise wall is $89,975 per

benefited receptor (see Table C-69, Appendix C). The approximately 305-

foot long, 9-foot high noise wall does not meet MnDOT’s cost-effectiveness

criteria; therefore, the analyzed noise wall is not proposed.

approximately 305-foot long, 8-foot high noise wall would cost $83,875, and

The approximately 305-foot long, 8-foot high modeled noise wall does not

meet MnDOT’s minimum 7 dBA noise reduction goal to be considered

reasonable. Therefore, the analyzed noise wall is not proposed.

Modeled Noise Wall F6 (West Side of TH 241, Between Eastbound I-94

Exit Ramp and Westbound I-94 Entrance Ramp) (Receptors TR48 through

TR52)

Modeled Noise Wall F6 is located along the west side of TH 241 between the

eastbound I-94 exit ramp and the westbound I-94 entrance ramp. Modeled

Noise Wall F6 is behind the curb along southbound TH 241 adjacent to a

proposed trail. Modeled Noise Wall F6 includes a gap to accommodate the

entrance loop ramp from westbound I-94 to TH 241. Modeled Noise Wall

F6 is approximately 785 feet long (see Figure A-9, Appendix A).

A 308-foot long segment of Modeled Noise Wall F6 is on the TH 241 bridge

over I-94. A noise wall that is located on a bridge must meet crash impact

specifications and be lightweight. Because of these requirements, a noise wall

on a bridge has a greater estimated construction cost compared to the

standard MnDOT noise wall construction cost of $20 per square foot. The

estimated cost for a test level-4 (TL-4) crash tested noise wall is $136 per

square foot.



approximately 785-foot long, 20-foot high noise wall would cost $1,067,735.

This cost includes 477 feet of glue laminated rub rail at a cost of $115 per

square foot. The cost-effectiveness of the approximately 785-foot long, 20-

foot high noise wall is $1,067,735 per benefited receptor (see Table C-77,

Appendix C). The approximately 785-foot long, 20-foot high noise wall does

Southeast Quadrant of I-94/TH 241 Interchange (Receptors 275 and

276)

Receptors 275 and 276 represent commercial properties located in the

southeast quadrant of the I-94/TH 241 interchange in St. Michael (see Figure

A-9, Appendix A). Modeled noise levels at Receptors 275 and 276 are

projected to be below State daytime and nighttime standards for NAC-2

under the 2040 Build Alternative. Therefore, noise walls were not evaluated

at this location.

Northeast Quadrant of I-94/TH 241 Interchange

The northeast quadrant of the I-94/TH 241 interchange is undeveloped. The

northeast quadrant of the I-94/TH 241 interchange consists of a 100-year

floodplain and floodway associated with the Crow River. There are no noise

receptors in the northeast quadrant of the I-94/TH 241 interchange.

Therefore, noise walls were not evaluated at this location.

Other Noise Mitigation Techniques

Noise abatement measures other than noise walls were considered but

determined not feasible and reasonable for the proposed project. These

measures are summarized below.

• Traffic Management Measures: These measures include such

items as prohibition of certain vehicle types and time-use restrictions

for certain vehicle types. These traffic management measures are not



reasonable for the I-94 St. Michael to Albertville Project. These

measures would be inconsistent with the function of I-94 as a

principal arterial, interstate freeway.

• Modified Speed Limits: In general, a decrease in speed of

approximately 20 mph is necessary for a noticeable decrease in noise

levels. The existing posted speed limit on I-94 is 70 miles per hour

(mph). Lowering speed limits on I-94 would be inconsistent with its

function as an interstate freeway. In addition, motorists would likely

not obey a substantially lower speed limit.

• Vertical and Horizontal Alignment: Substantial changes in the

horizontal and vertical alignments of the project segment of I-94 and

the I-94/TH 241 interchange are not feasible. The proposed I-94 and

TH 241 improvements are located within existing highway right of

way, avoiding right of way impacts to adjacent properties. Changes in

the vertical alignment of I-94 are not part of the project scope. The

proposed vertical alignment of TH 241 over I-94 was identified to

provide the required vertical clearance between the TH 241 bridge

and I-94.

• Landscaping/Natural Noise Screening: Vegetation is only

effective for reducing noise levels if it is at least 100 to 200 feet deep,

a minimum of 15 feet above the line of sight, and dense enough that

it cannot be seen through (e.g., evergreen vegetation, which maintains

its foliage year-round). It is not feasible to plant enough vegetation

within existing and proposed right of way to achieve substantial noise

level reductions. As such, vegetation is not a reasonable noise

mitigation measure.

• Exclusive Land Use Designations: Buffer zones are undeveloped,

open spaces adjacent to a roadway corridor. Much of the I-94 project

corridor is already developed. Residential and commercial land uses

are located along I-94 from west of CSAH 19 to the CSAH 37

interchange in Albertville. Residential land uses are in St. Michael

along the north and south sides of I-94 west of TH 241, and

commercial land uses are located at the TH 241 interchange. There

are lands adjacent to the I-94 project corridor between CSAH 37 and

TH 241 that are currently in undeveloped, agricultural uses. Future

land uses adjacent to I-94 between CSAH 37 and TH 241 are guided

towards commercial, industrial, and business park/office uses.

Because of the large amount of land necessary to accommodate

buffer zones, acquisition of land to create buffer zones is not feasible.

See below for a discussion of land use planning and traffic noise

(“Land Use Planning Analysis” section).



• Noise Insulation of Non-Residential Buildings: Under the

MnDOT Highway Noise Policy, only non-residential buildings such

as schools, hospitals, and places of worship should be considered for

acoustical insulation if there are no exterior areas of frequent human

use associated with the property. However, it is also important to

note that acoustical insulation of non-residential buildings would not

affect noise levels that exceed Minnesota state noise standards

because Minnesota state noise standards are intended for exterior

uses only.

There are no schools, hospitals, or places of worship within the

project area.

Land Use Planning Analysis



The prevention of future traffic noise impacts is a critical component of

noise control. Local governments, through their authority to regulate land

development, can help prevent future traffic noise impacts by prohibiting

noise-sensitive land uses from being located adjacent to a highway or by

ensuring that developments are planned, designed, and implemented in such

a way as to minimize noise impacts. The following analysis provides

information regarding modeled noise levels adjacent to I-94 in Albertville

and St. Michael for use in community and land use planning.

Undeveloped land is located adjacent to I-94 between CSAH 37 and TH 241

in Albertville and St. Michael. This undeveloped land is guided towards

commercial and industrial uses in Albertville and business park/office and

commercial uses in St. Michael. Figure 4 illustrates future planned land uses

in Albertville. Figure 5 illustrates future planned land uses in St. Michael.

Traffic noise levels were modeled at representative receptor locations along

I-94 at incremental distances from existing and proposed right of way limits

under future (2040) Build Alternative conditions (approximately 50 feet, 100

feet, 150 feet, 200 feet, 250 feet, 300 feet, 350 feet, 400 feet, 450 feet, and

500 feet from the I-94 right of way limits) (see modeled receptor locations in

Figure A-5, Appendix A). This analysis was based on existing topography

adjacent to the project segment of I-94, and assumed no intervening barriers

or structures between the modeled receptor locations or project area

roadways. Table 5 lists the results of the land use noise modeling analysis for

future (year 2040) daytime and nighttime Build Alternative conditions.

Results from the land use planning analysis indicate that modeled traffic

noise levels under 2040 Build Alternative conditions would exceed State

daytime and nighttime L10 standards for NAC-2 at distances up to 250 feet to

350 feet from the I-94 right of way. State daytime and nighttime L50

standards for NAC-2 would be exceeded at distances greater than 500 feet

from the I-94 right of way.

It is important to note that these results are representative traffic noise levels,

given the assumptions listed above (e.g., existing topography, no intervening

structures or barriers, etc.). The results of this analysis can be used as a guide

for local governments responsible for land use planning and land use

controls to help prevent future traffic noise impacts on currently

undeveloped lands. Setback distances, along with other techniques (e.g.,

earthen berms, noise barriers, site plan elements/design), can be used to

ensure that the desired compatibility between I-94 and potential future

development is achieved.

Conclusions and Recommendations


Conclusions and Recommendations

Construction of the I-94 St. Michael to Albertville Project is anticipated to

increase modeled future traffic noise levels compared to existing conditions.

Daytime L10 modeled noise levels are predicted to range from 55.8 dBA to

88.7 dBA under the 2040 Build Alternative. Daytime L50 modeled noise levels

are predicted to range from 53.9 dBA to 81.3 dBA under the 2040 Build

Alternative. Daytime traffic noise levels are projected to increase by

approximately 0.2 dBA to 2.9 dBA (L10) compared to existing conditions.

Nighttime L10 modeled noise levels are predicted to range from 55.8 dBA to

88.0 dBA under the 2040 Build Alternative. Nighttime L50 modeled noise

levels are predicted to range from 53.9 dBA to 82.5 dBA under the 2040

Build Alternative. Nighttime traffic noise levels are projected to change by

approximately -0.1 dBA to 3.2 dBA (L10) compared to existing conditions.

Modeled noise levels are predicted to exceed State daytime L10 standards at

294 modeled receptor locations with the 2040 Build Alternative, and exceed

State daytime L50 standards at 382 modeled receptor locations with the 2040

Build Alternative. Modeled noise levels are predicted to exceed State

nighttime L10 standards at 416 modeled receptor locations, and exceed State

nighttime L50 standards at 433 modeled receptor locations with the 2040

Build Alternative.

Noise walls were evaluated along the I-94 project corridor at modeled

receptor locations that are projected to exceed State daytime and/or

nighttime standards under 2040 Build Alternative conditions. Modeled noise

walls were determined to be not acoustically feasible (i.e., modeled noise

walls did not meet MnDOT’s minimum 5 dBA reduction) or reasonable (i.e.,

modeled noise walls did not meet MnDOT’s noise reduction design goal or

did not meet MnDOT’s cost effectiveness criteria). Therefore, no noise walls

are proposed as part of the I-94 St. Michael to Albertville Project.
